Thanks, I understand what you are talking about however I am having trouble putting it into action.
My data has DealTags which is “list of text” which contains what I want to search against. When I then do the data source in the repeating group I am chosing “do a search” and picking Deal, then doing the constraint DealTags “contains” (it doesn’t give me any other option that makes sense) my custom built list of tags from clicking elements.
I have tried writing it the other way around but I can’t get the syntax to work at all.
The only time I have seen “is in” as an option the field is not a list so I don’t think that will work for me.
